Аннотация:Abundant resources and low prices make natural gas very attractive as petrochemical feedstock and increase the interest to its oxidative conversion to basic petrochemicals. The paper presents results of gas-phase oxidative conversion of light C2–C5 alkanes diluted by nitrogen, helium or methane ([CnH2n+2]0 < 5%) at low oxygen [O2]/[CnH2n+2]= 0.2–1, atmospheric pressure and temperatures 500–750 C. Even significantly diluted, light alkanes display a chain-branching behavior at oxidation with a sharp transition trough a self-ignition limit. Oxygen significantly increases conversion and decreases reaction time, especially at intermediate temperatures below that of thermal cracking. The nature of
diluting gas significantly influences on the process.
